I used the same method and it did work for me, but it kind of took awhile to come off, it took 5 tries for it to go away..

Firstly, when claying your car you'll need to use a quality QD for a lube between the clay and paint surface. The quick detailer enables a better lubricity than water will/does.

I have a feeling clay will remove most of the marks and then a light polishing should most likely take care of whatever is left. Did you already get your polish as well? Pads?

QD = Quick Detailer

You'll probably want to try polishing with the white pad AFTER you've clayed the car. I'm sure the water etching (if any are left) will come out with the white pad using a somewhat fine grade of polish. You bought a great kit .......... something else you'll want to do when polishing is to spritz the polishing pad with some of the QD to help the polish to spread and not dry out to quickly.

Polish and wax are different.

Polish is mainly used to remove lite to medium defects in the paint. Compounds are a very abrasive form of polish for heavily marred paint and/or deep scratches. Compound used by someone inexperienced can damage a car's paint in no time.

Wax is a protective coating that really has limited longevity. Most people will use wax as an intensifier to the paint for a deeper gloss/shine. Typically, wax will last 1-2 months depending on what type of environment (daily driver, parked outside, frequency of washes).

Sealer gives a longer lasting protection however it doesn't give the added beautification of the wax. This is why many people who use a sealer will also top the sealer with a quality carnauba wax. Sealer typically lasts 3-5 months again, dependant on the variables.

I prefer to seal only after polishing and then maintaining with a carnauba wax afterward.

You can use it on the windows IF you have no other alternative. The glass can also be cleaned using Windex and mild steel wool. Don't use the steel wool on the mirrors ........ just the door windows and front & back winshields.

To prevent getting any compound, polish and/or wax on the exterior trim you'll want to mask these areas off with blue painters tape. I say the painters tape because it leaves no residue behind, adheres well and is easy to remove when you've finished polishing the paint.

If you already have compound on the trim then I'm guessing you may have rub marks from the buffer pad as well, right? If this is the case then all you can do is dress the black trim with a trim cleaner/dressing/restorer. If you do have rub marks then they are most likely there to stay until you replace the trim.
To remove just the compound from the trim you could lightly clean the areas with a scotch bright pad and cleaner like Goo-Gone. Mask off the painted areas to keep from scratching the paint first. Only use enough product for that particular spot so as to not have product reaching the paint.

I like the Menzerna products thru Detailed Image for polishing. As far as wax goes I'm pretty biased in that I like the Dodo Juice soft waxes. I've heard great things about Natty's Blue and have had great results with Chemical Guys 50/50 & Pete's 53. All of these are found on DI.

My favorite these days is the Supernatural ... spendy @ $200 though. I'll try Swissvax next ......
